The Dormer Pramet C126 3.0 mm HSS-E-Powder Metallurgy TiCN-coated slot drill is built for precision in tight, small-diameter milling tasks. It’s ideal for shoulder milling, slot milling, and ramping in a range of ferrous and non-ferrous materials, delivering consistent results in compact CNC operations.

• Diameter: 3.0 mm
• Length of Cut: 5 mm
• Overall Length: 49 mm
• Flutes: 2
• Shank: Flatted 6 mm Weldon shank
• Material/Coating: HSS-E with TiCN coating (powder metallurgy)
• Helix and Rake: 30° helix, 12° rake for efficient cutting and smooth chip flow
• Standard: DIN 327 D
• Applications: Shoulder milling, slot milling, and ramping in free-machining steel, plain carbon and alloy steels, cast iron, copper/copper alloys, and titanium/titanium alloys

Equipped with a TiCN-coated HSS-E profile and a compact, rigid short design, this drill delivers clean slots and precise shoulders with strong wear resistance. The powder metallurgy process enhances toughness and edge retention, while the TiCN coating helps reduce built-up edge for steadier cutting and better surface finishes. The 3.0 mm diameter makes it ideal for narrow slots and fine-detail work, and the flatted shank provides secure seating and repeatable performance in dedicated tool holders. Use this drill when you need reliable accuracy in small features across a variety of common engineering materials, from steel and cast iron to copper alloys and titanium.
